Optimal Hardware On A $4,500 Budget
Here the inverter size will change due to use of more power rating appliances if you compare to our lower budget options. Components such as batteries, solar charge controller size and the solar panels increase in number due to change of components power rating and different hours of use too.
Solar Charge Controller – Y-SOLAR 60A/80A 960W/1920W 12V/24V
Final Price: $4,064
At only $4,500 you will have solar energy system up and running at a basic level of appliances usage. We increased it to $4,500 from $4064.06 due to some cable and connector purchases.

Premium budget ($4,500)
- Total watts = 2770 watts
- Total watt-hours =8460 watt-hour
Remember:
- Generation factor=2.98
- Battery losses=0.85
- Battery depth of discharge=0.6
- Solar charge controller losses=1.3
- Inverter watts allowance=30%
Sizing for components:
Solar panel
8460watt-hour/2.98= 2838.9watts
2838.9watts/160watts=17.74=16,160watts solar panels
Inverter
(0.30×2770) +2770watts=3601=3500watts inverter
Battery bank
8460watt-hours/0.85/0.6 = 16588.23watt-hours
16588.23watt-hours /24 volts = 691.176AH
691.176AH/200AH = 4.45 = 3,45 = 3/4, 200AH batteries
Solar charge controller
7.09A x1.3 x9 = 129.038A = 130A charge controller

System specifications
- Our solar panels are connected in two pairs. Each pair has 8 solar panels connected in parallel and the two pairs are connected in series. This way the output current will be for 8 solar panels and the voltage will be 24volts
- Our solar charge controller is 24 volts
- Our batteries are 24 volts, so they will be connected in parallel so as to Power our 24 volts inverter
Conclusion
The bottom line here is that if you´re looking to build an awesome home off grid solar system on a $4,500 budget, that will last you for many years and give you a very powerful system that will erase any further electrical bills for you. Then this one is without a doubt the one for you. So, what are your thoughts on this build? Are you gonna build it yourself? I will be more than happy to answer any questions you might have.
